Warning light on? Let's find out why.

Modern cars monitor hundreds of systems, and a warning light can mean anything from a loose fuel cap to a failing sensor or a serious engine fault. A scan tool shows where the car thinks the problem is.

Testing the circuit or component confirms it, so you only pay to fix what's actually broken.

Diagnostics questions

Can Kartech diagnose a warning light?

Yes. Kartech scans the vehicle's systems for fault codes, reads live data and tests the suspect components to confirm the cause before recommending a repair.

Is it safe to drive with the check engine light on?

If it's steady and the car drives normally, it's usually safe to drive to the workshop soon. If it's flashing, or the car is overheating or losing power, stop driving and call.

Will clearing the code fix the problem?

No. Clearing a code only switches the light off. If the fault is still there, the light will come back.
